As I said, that crank is not a stout piece. If it's out, and to me it sounds like your shop guys purely guessing (and guessing wrong), that crank won't last with much abuse. It's cheaper to pull it out and fix it, than replace it when the crank breaks.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
